Note：When install pole type：load cell plug in the bottom of the indicator；
When install desktop: load cell plug in the back of the indicator；
▲ ！warning:：Weighing indicator power supply must be cut off when install the
load cell and wire connecting must be correct and reliable.
▲ ！warning ：To ensure the system is working fine , please fix the plug with screw
to the indicator after the signal source wiring, the user can not insert and pull out
plug at discretion, and it is forbidden while the indicator is on .
▲！Signal source and weighing indicator are all static electricity sensitivity
equipment，so user must adopt anti-static electricity when weighing indicator
works. To avoid the damage of the signal source and weighing indicator by
lighting strike and insure the operator's safety and correlative equipment working
well in the thunder storm season, the user must adopts credibility measures to
avoid lighting strike.

Chapter 6 Maintenance and attention
1.To guarantee its clarity and service life, the indicator shouldn’t be placed directly under
sunshine and should be set in the plain space.
2.It is not suitable to place the indicator in the dusty and vibration environment and also
avoid using in the moist environment.
3.Signal source and weighing indicator should be reliably connected, and system should
be well grounding. It should be far away with strong electric field, strong magnetic field.
Load cell and indicator should be far away with strong corrosive, inflammable, explosive
object.
▲Do not use under inflammable gas or inflammable steam; do not use under
pressure container canning system.
▲Lightning frequent areas, it must be installed reliable lightning arrester, to ensure
operators safety and prevent damage of instruments and relevant equipment due to
lightning.
▲Signal source and indicator are static sensitive equipments, when using must
earnestly adopt anti-static measure. It is prohibited in measuring device for welding
operation or other strong electric field operation; in thunderstorms season, we must
implement the reliable lightning-protection measures to prevent signal source and
the indicator damage caused by lightning strike, ensure operators safety of weighing
equipment and related equipment safety operation.
4. Never use strong solvents (e.g., benzene, nitro class oil) to clean the housing.
5. Liquid or electricity conducting particles should not be poured into the indicator, in case
the indicator damage and electric shock.
6. You should cut off power supply of indicator and relevant device before you pull-in and
out the connecting cable of indicator and external device.
▲！You should cut off power supply before pull-in and out connecting cable of signal source.
7.Output interfaces of indicator must be strictly in accordance to the user's manual, you
should not alter any connection. If there is failure when using the indicator, you
should immediately unplug it, and send to manufacturers for repair. Ordinary
non-professional manufacturers should not repair it to avoid bigger damage.
8 . Company advice for customers: start to use our indicator after test. The company is
only responsible for the quality of indicator, the biggest compensation is not more than
twice of indicator value, the company is not responsible failure of the whole system.
9. The built-in battery of indicator is a consumable part that is not within the range of "three
guarantees".
▲！In order to prolong the battery service life, ensure fully charging before using. If
indicator has not been used for a long time, it must be charged every two months,

X K 3 1 9 0 –A26
() 18
every time 20 to 25 hours.
(Note：Charging time is around 20-25 hours and the indicator must be power off)
▲！When moving or installing the indicator, you must carefully move it and avoid
strong vibration, impact or bump in order to avoid electrode in the battery being
shorted and damaged
10. Since invoice date, the indicator has a one-year free repair period. If any
non-artificially failure happens under regular using conditions within this period, the user
can send the indicator with its guarantee card (of the correct number) back to our service
station or supplier for repair. The indicator shouldn’t be open without authorization ,
otherwise free guarantee will be cancelled.
